In this study, ZnSnO₃/NiO heterostructures were synthesized using a co-precipitation method followed by an annealing process. The gas-sensitive characteristics of the sensors based on these samples were evaluated. The results indicate that the sensor performance was optimized when the molar ratio of Ni to Zn was 1∶2. Specifically, the response values of the ZnSnO₃/NiO-2-based sensor to 100 μL·L^-1 triethylamine (TEA) gas at 220 ℃ reached 70.6, which were 6.1 times higher than that of the pure ZnSnO₃ based sensor. The findings demonstrate that ZnSnO₃/NiO heterostructures exhibited not only short response and recovery times (1 s/18 s) but also good gas selectivity, repeatability, and long-term stability. The enhanced sensing mechanism has been investigated in detail.

面向化学类(非高分子)专业的高分子化学实验教学发展较为缓慢，亟需紧跟研究前沿，引入新内容。本文总结了近十年的教学改革经验，并以温敏型高分子的制备、溶液性质、光学性能与应用为例，介绍如何通过实验教学内容、实验技术、教学方法等方面的创新，设计符合理科人才培养需求的、契合时代与科学发展的、被学生喜爱与重视的一系列高分子化学实验，以有效解决培养需求与课业负担之间的矛盾，且在不新增开课、课时有限的情况下，加入到化学类专业本科教学体系中，激发学生对学科领域的兴趣，提升学生的探究和创新能力。

本文在科产教融合理念下，对“现代分析技术”进行了课程改革。主要基于校内/际/企合作实现优质师资共享，通过融入科学前沿和生产实际丰富教学内容，在授课中采用教师主导、学生自主探究、“理虚实”结合、线上线下协同、公众号辅助等多维教学模式，同时配备多元化考核评价体系促学促教。实践结果表明，教学质量得到了明显提升，极大地助力于理论知识、科学研究、生产实践兼顾兼优的复合型人才的培养。
